Xin Wang Lab: Neuroapoptosis Drug Discovery

My group focuses on the identification of candidate therapeutics and potential targets for therapeutic intervention in neurodegenerative disorders including Huntington’s Disease, Stroke, Amyotrophic Lateral Sclerosis and Alzheimer’s Disease. Another main interest concerns the molecular and cellular apoptotic mechanism of neurodegenerative diseases, because a greater understanding will help in the development of new therapies that act on disease genes. We also work on chemistry and structure-activity relationship and stem cell therapy.
